高中物理比较抽象,学生普遍感觉比较难,所以一定量的习题是必不可少的.如何讲解习题才能起到很好的效果呢?,习题变式教学是一种很好的办法,结合本人的教学实践谈谈习题变式教学的应用与思考.一、物理概念教学中采用变式教学有利于学生分清、把握概念的本质属性.例题1高三物理第一轮复习,复习电场力做功这一概念时笔者给学生做了这样一个题目:光滑的水平面上存在着水平向右场强为E的匀强电场,有一个质量为m,带电量为+q的小
High school physics is more abstract, students generally feel more difficult, so a certain amount of exercises is essential .How to explain the exercises in order to play a very good effect ?, Exercises variant teaching is a good way, combined with my Teaching practice to talk about the application of variant teaching exercises and thinking First, the teaching of physical concepts using variant teaching is conducive to students to distinguish and grasp the essential nature of the concept .Example 1 3 junior high physics review, review the concept of electric field work force When I gave the students to do such a topic: there is a smooth horizontal plane to the right field strength of E uniform strong electric field, there is a mass of m, the charge is + q small
